# Engineer

An Engineer is a citizen who has an [Engineer Certificate](https://docs.deepmine.world/deepmine/deepmine-gaming-nfts/badges/engineer-certificate). Engineers are passionate mechanics who ponder every day over how to move technology forward. Engineer's skills allow improving mining equipment. 

* The Engineer Certificate allows the player to produce NFTs that apply upgrades to the mining equipment. 
* To become an Engineer, the player needs to collect nine pages of an [Engineers Diploma](https://docs.deepmine.world/deepmine/deepmine-gaming-nfts/badges/engineers-diploma-page) and exchange them for an Engineer Certificate in the government.
* Engineers diploma pages can be found in equipment packs, which [Factories ](https://docs.deepmine.world/deepmine/deepmine-gaming-nfts/factory)produce. The chance of producing a pack with a diploma page inside is higher with each factory level upgrade.  
* Engineers spend DMP/DME for the production of upgrades.
